MC14076B数据手册集成电路（IC）的触发器规格书PDF

描述 Description

The MC14076B 4-Bit Register consists of four D-type flip-flops operating synchronously from a common clock. OR gated output-disable inputs force the outputs into a high-impedance state for use in bus organized systems. OR gated data-disable inputs cause the Q outputs to be fed back to the D inputs of the flip-flops. Thus they are inhibited from changing state while the clocking process remains undisturbed. An asynchronous master root is provided to clear all four flip-flops simultaneously independent of the clock or disable inputs.

特性 Features

• Three-State Outputs with Gated Control Lines
• Fully Independent Clock Allows Unrestricted Operation for the Two Modes: Parallel Load and Do Nothing
• Asynchronous Master Reset
• Four Bus Buffer Registers
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Capable of Driving Two Low-Power TTL Loads or One Low-Power Schottky TTL Load Over the Rated Temperature Range
• Pb-Free Packages are Available*

简介

MC14076B属于集成电路（IC）的触发器。由制造生产的MC14076B触发器触发器是能够存储单个逻辑状态或信息“位”的基本数字存储器件。这些器件至少有两个输入；一个或多个用于传递要存储的数据，另一个用于指示存储该数据的时间点。不同的触发器类型，例如 D（延迟）、SR（置位复位）和 JK，对提供给其输入的信号有不同的响应，可用于实现不同的逻辑功能。这些器件与锁存器的不同之处在于它们是边缘敏感器件，其保持的逻辑状态仅在接收到有效时钟信号时才会改变。
